A water outlet of a thermal source tower is connected with a liquid inlet of the evaporator through a first control valve, and a water inlet of the thermal source tower is connected with a liquid outlet of the evaporator through a second control valve. The solar auxiliary thermal source tower heat pump system further comprises a solar heat collection device which is in parallel connection at two ends of the liquid inlet and the liquid outlet on the evaporator through a pipeline and the thermal source tower. The thermal source tower and the solar heat collection device are in parallel connection and can work simultaneously or be switched to work individually to be suitable for different weather environments. Thus, a stable and reliable thermal source can be provided for the thermal source tower heat pump machine seat.

Description

A kind of solar-assisted heat source tower heat pump
Technical field
The utility model relates to technical field of heat pumps, particularly a kind of solar-assisted heat source tower heat pump.
Background technology
Heat source tower is to make working media and air carry out heat exchange, thereby the equipment of Cooling and Heat Source is provided for the heat source tower heat pump unit.In the prior art, a kind of heat source tower heat pump system is arranged, comprise heat source tower and source pump, source pump comprises housing and is arranged at the interior thermodynamic cycle pipe of housing, the delivery port of heat source tower links to each other with the inlet of thermodynamic cycle pipe by the first control valve, and the water inlet of heat source tower links to each other with the liquid outlet of thermodynamic cycle pipe by the second control valve.In the winter of cold, heat source tower directly gathers outdoor low-grade energy, utilizes low enthalpy salt circulation solution to form the clammy air that liquid film is direct and enthalpy is higher on heat exchange layer surface and fully contacts, and cold is passed to air.This transmission of heat by contact is so that the temperature of periodic duty liquid levels off to outdoor air wet bulb temperature, thereby provides stable thermal source source for the heat source tower heat pump unit.
Source pump couples together compressor, evaporimeter, expansion valve, condenser by refrigeration pipe and forms a closed therrmodynamic system.Compressor sucks the low-temp low-pressure gas refrigerant from evaporimeter, be compressed into the gas of HTHP, enter condenser and water heat-shift, in condenser, be cooled into cold highly pressurised liquid, temperature constantly raises behind the heat of water absorption refrigeration agent, high pressure liquid refrigerant is behind the expansion valve reducing pressure by regulating flow, become the gas-liquid two-phase mixture of low-temp low-pressure, in evaporimeter, pass through under the effect of fan, absorb airborne heat of vaporization and become gas, and then by compressor suction compression, go round and begin again, thereby constantly provide thermal source for the external world.Its weak point is: at winter and transition season, when sunlight was reasonable, dry-bulb temperature was high, wet-bulb temperature is low, cause the reduction of heat exchange efficiency, energy consumption of heat source tower increase large, heat supply is not enough.
Solar energy is as a kind of regenerative resource, and its aboundresources both can freely use, and need not again transportation, and without any pollution, winter and transition season still can be collected a large amount of thermals source preferably at sunlight to environment.Wait greatly characteristics but solar energy has intermittent and changed by meteorological condition, so that solar energy is affected by Changes in weather is larger, cause solar-heating unstable.Therefore, if heat source tower heat pump system and solar energy are organically combined, the two complementation then can fully guarantee the reliable and stable heat supply of source pump.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, and solar energy and heat source tower are organically combined, and a kind of environmental protection and energy saving, economical operation, heat supply is reliable and stable and climate adaptability is strong solar-assisted heat source tower heat pump are provided.
The purpose of this utility model is achieved in that a kind of solar-assisted heat source tower heat pump, comprise heat source tower and source pump, described source pump comprises compressor, condenser, expansion valve and the evaporimeter of successively closed loop connection, the delivery port of described heat source tower links to each other with the inlet of evaporimeter by the first control valve, the water inlet of heat source tower links to each other with the liquid outlet of evaporimeter by the second control valve, also include solar energy heat collector, solar energy heat collector is connected in inlet and the liquid outlet two ends of evaporimeter in parallel by pipeline and heat source tower.
Described solar energy heat collector comprises collecting plate, heat collection water tank and cyclic water tank, and collecting plate links to each other with heat collection water tank, and the heat-exchanging component that arranges in heat collection water tank and the cyclic water tank links to each other; The delivery port of described cyclic water tank links to each other with the inlet of described evaporimeter by the 3rd control valve, and the water inlet of cyclic water tank links to each other with the liquid outlet of evaporimeter by the 4th control valve.
During the utility model work, at sunlight preferably winter and transition season, the first control valve and the second control valve can be closed, make heat source tower be in off working state, simultaneously, open the 3rd control valve and the 4th control valve, solar energy heat collector is worked independently: the collecting plate heat collection water tank that heat transferred is coupled of having collected a large amount of solar energy, and then heat collection water tank again with thermal energy transfer to heat-exchanging component, heat-exchanging component heats the water in the cyclic water tank, if water temperature reaches the instructions for use that air-conditioning heating is used, then directly deliver to the indoor load side by water pump and carry out heating, if water temperature is not enough, then control valve is sent into the heat exchanger coil of condenser, after again being heated by the heat source tower main frame heat source water is delivered to indoor, thereby be reached for the air-conditioning heat supply or produce domestic hot-water's purpose; At the rainy weather of cold, the relative solar energy heat collector of the operating efficiency of heat source tower is higher, and can open the first control valve and the second control valve this moment, closes the 3rd control valve and the 4th control valve, makes heat source tower be in the state of working independently; When source pump needs a large amount of heat supply, can open simultaneously four control valves, heat source tower and solar energy heat collector are worked simultaneously, thereby the thermal source of capacity is provided for source pump, guarantee the reliable and stable work of source pump.
Compared with prior art, the beneficial effects of the utility model are: be arranged in parallel solar energy heat collector with heat source tower, can realize that the two is the source pump heat supply individually or simultaneously, for the heat source tower heat pump unit provides reliable and stable thermal source source; Can use separately high efficiency heat source tower in overcast and rainy season, and at sun-drenched winter and transition season, can use separately solar energy heat collector, not only energy-conserving and environment-protective, economical operation and climate adaptability that can the Effective Raise heat pump.
